Really looking forward to it. I had the return of lead legs on Friday morning for R2 (only the last 5 min section), but was running up a slight incline for most of it, so will switch back to my usual route tomorrow, which is pretty much flat the whole way. Thanks to everyone who commented on my last (first!) post - I tried taking one of my earpods out for a minute to check out my breathing, and it was JUST LIKE an old wheezing man! It gave me a good laugh, which got me through the last couple of minutes.
Still waiting for my new running shoes to arrive - had to order a size 8 (8!!?), although the nice man in the shop assured me that it's normal for running shoes to come up a size bigger. I'm currently running in 8 year old very cheap trainers, so I'm hoping that new shoes will be like new tyres!
